Abstract

PURPOSE:To surely control feed of a recording paper even driven with just a driving motor and to minimize the size of a case of a facsimile device, by connecting a heat-sensitive recording head via a coupling member, to a telephone stage which varies its position between the reception queuing mode and the transmission mode. CONSTITUTION:Both a platen roller 12 of the reading side and a platen roller 8 at the writing side are driven by a driving motor 7. A heat-sensitive recording head 9 is connected via a coupling member 20 to a telephone stage 5 which changes its position between the reception queuing mode and the transmission mode. As a result, the head 9 detdetached from the roller 8 in the reception mode. This prevents the feed of the recording paper in the transmission mode. Furthermore no feed variance is caused for both the original and the recording paper in the transmission and reception modes since the rollers 8 and 12 are always in the driving state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile machine using a small volume thermal recording head.

Conventionally, in order to reduce the size of the device, one platen roller was driven by two drive motors, and the platen roller was configured so that the sending paper was passed through the top surface and the receiving paper was passed through the bottom surface of the platen roller. exists. And, in receiving Confucianism, the platen four-
A thermal head is provided which is biased toward 2.
In order to prevent the recording paper from being fed out during transmission, it is necessary to install a solenoid in the recording paper feeder 111 for switching the recording paper! It opens. However, if such a configuration is adopted, it will be possible to avoid problems such as
It is expensive and has few functional benefits.

The present invention takes advantage of these disadvantages, and provides a tour erecting device in which recording paper is reliably controlled even when it is dynamically driven by two drive motors. The purpose is to obtain.

The present invention drives both the platen roller on the reading side and the platen roller on the writing side in the evening, and connects the telephone set to a thermal sensitive telephone set via a connecting member, the position of which changes between standby for reception and transmission. Since the recording heads are connected, the thermal recording head separates from the platen roller during transmission, and as a result, the recording paper is not fed properly during transmission.
An embodiment of the present invention will be described with reference to FIG. First, an operation panel (2) is provided on the front side of the main body case (1) and is formed with an inclination 1i.
A received paper ejection sheet ml (S) is formed below.

A document insertion table (4) is formed on the upper surface of the main body case (1) and is inclined so as to become deeper toward the top. A telephone mounting stand (5) that moves back and forth is provided on the upper surface of the main body case (1). In addition, the main body case (1) (D ``M' t
A document ejection hole (6) is formed in hI.

Next, a drive motor (
7) is installed. A platen roller (8) and a thermal recording head (9) are provided in the hand, and the drive motor (7) is used to pull out recording paper from a recording paper roll (7) located on the same axis. An α arrow is inserted between the thermal recording head (9) and the platen row 2 (8). Also, at the rear of the upper part of the main body case (1), there is a platen roller (2), a reading sensor (toward), and (8)
) al K are provided with wheels α◆), which are connected to the endless band Akebono 1 between these wheels (4401 and the motor shaft (B) of the drive motor (7)), and are connected to each platen roller (8). ) and (2) are configured to be driven simultaneously.

Therefore, the switching lever - 〇 center, which is a connecting member bent in a dogleg shape, is rotatably attached to the fixed shaft (to).
One end of this cutting bar 4 is connected to the thermosensitive recording head (9), which is installed so as to be able to move up and down slightly, by means of a bottle (2). Further, a bin (2) is fixed to the other end of the switching lever 610, and this bin 4 is connected to the telephone device mounting stand (
5) A long hole fJ of a predetermined length in the connecting plate (2) integrated with
It is inserted in 4. Note that the symbol - is the electrical component υ, and the symbol - is the telephone.

In such a configuration, the state shown in FIGS. 1 and 2 is the reception standby state, and the state shown in FIGS. 3 and 4 is the transmission state. When a reception signal is input during reception standby, the drive motor (7) is started, and the two rotors (8) and (2) are simultaneously driven by the endless belt α to (to). At this time, since the recording paper (b) is held between the platen sheet (8) and the thermal recording head (9), it is ejected from the receiving paper ejection window (3) at a constant speed.

At this time of reception, the telephone mounting base (5) covers the entire body case (1) and functions as a protective cover.

However, when I went to send a message, the turtle had a phone mounting stand (5).
to expose the document insertion table (4). By this movement of the telephone mounting stand (5), the edge of the elongated hole rotates the magJ replacement lever. This is K, Shibin (2) went up and pulled up the thermal recording head (9),
Separate from the platen roller (8). In this state, when a document (not shown) is placed on the document insertion table (4) and the send button is pressed, the drive motor (7) is started and drives the two platen rollers (8). As a result, the original is fed out toward the original discharge hole (6) and read while being held between the platen roller (6) and the reading sensor. However, even when the platen roller (8) rotates, the thermal recording head (9) is separated, so no driving force is applied to the recording paper (B), and the recording paper (41) is fed out. Never.

In the present invention, as described above, the position of the thermal recording head is changed via the connecting member by the movement of the telephone device mounting stand, which changes its position between reception standby and transmission. Even if the platen roller of the sensor couple and the platen row 2 on the thermal recording head side are driven at the same time, the recording paper will not be fed out during transmission, but will be fed out only during reception. , the main body case can be made extremely compact, and by using only one drive motor, recording paper feed control can be performed reliably even if wrinkles occur, and there is no functional problem. Since the two O-platen rows 2 are both driven, there is an advantage that there is no possibility of uneven feeding speed.
